If it happens I'll be thrilled, but I think the odds of him returning are slim.
And if there's one guy I'd be willing to put into our HC slot without OC experience it's Tim Rattay. I think the man can come up with a game plan and adapt as the game plays out.
Frankly IMHO, he should have been our OC the last 2 years. I could go off on a rant at this point but I won't.
